J. ECKER LOCK Filed Sept. 2O 1.921 3 Sheets-Sheet 5 and through bosses il 'formed interior-ly of 'the e sing, so that bolts or screws may be s through these holes :tor the purpose eide of the door.

o? seeurely @noting the :rising on the in- The other si(le,of theeasioff is partially closed hy means ot e. cover e l2, shown in Figures sind (l, which. o plate eittends substantially from pointosoli oli' the openings 9 to the opposite end of the easing. This cover plate is normally secured in posi tion by means of `screws passed through the countersunk holesl in theheek plate and threaded into tapped holes ih bosses lll, cast interiorly of the'casing 8, l*

The front Wall oil the easing is provided with an interior, lle-.t t'aee, over 7which a slide 'l5 is adapted to be slid bach and forth longitudinally oi the casing While guided tor Such .movement between parallel. ,guides 16 cest on seid fiat face.

Journalled for rotation in the front Wall of the easing is an arbor and manually rotated. nteriorly of the front Wall and spaced therefrom, said arbor carries a circular dise 19 and between the dise 19 and the front plate is positioned a cam 20, rigid with the arbor-"end preterably toi-ined integral thel'erit-h. The disc 19 is also rigid with thearbor and its .ieee opposite the carn-20 enr-ries an opstanding; fixed pin 2l. This' pin 21 is adapted for cooperation with a dog 22, the hub or which is journalled -for rotation in the back pluie l2. The hub 23 of the dog is positioned coaxial with the arbor 17 and a pin extends from the dog and enters a hole in the center of the circular disc 19., so as to maintain the parts coaxial. The rotation or' the dogg is adopted to bring either one oi' a pair shoulders into nient with thep'in 2l to impart rotation to the cani.

This rotation of the hub 23 is adapted to be imparted by a key through the agency of rotary loci; barrel of the' Well known Yale or Corbin type, which rotary lock barreis are Well known and in common use and need not be shown or further` set forthoin i, which extendsA :messie the outer end of the hub 23. ln mounting ,the lock on the door, the conventional lock barrel is mounted on the outsie of the door. the lock 2 of the present invention mounted interiorly of the door and the two connected by the recten ller rod referred to, so that the am may `e turned from the outsideof the door by means of a lrey associated with the loch, While said cani may be turned 1nteriorly of the door from the inside of the door by means of the knob 18.

rlhs earn- 20 Works in a cut out portion ot' the slide, which out out portion has a curi/ed edge 27. Through rotation of the cam 20, it is brought into engagement With the curved edge 2'? oi the out out portion and through this cooperation between-the parts,

sliding slide l5.

One end of the slide l5 is Provided with openings 28 adapted, when the slide isin unlocking position to register and coincide with the openings 9 formed in the iront wall of the' loch', so as to permit the passage of the studs 5 through the openings 28 and il. lwhen the parts are in 'these positions. The thickness ot the slide is, however, so proportioned at that part thereof in which the openings 38 are formed, that if the slide is retracted, while the studs are in the position described, that portion of the slide between the openings 28 and the forward end of the slide will be retracted beneath the orerhanging heads of the studs 5, as best shown in' Figure 4. Then this has been accomplished, it will be apparent that the withdrawal of the studs is impossible since the studs and 1the sliding plete of the lock are interlitted or interloeked in such manner as to preclude separation of the parts and consequent opening ot' the door until the locking plate of the lock has been retracted, either through the empio 'ment of the proper hey from the outsire of the door, or by manipulation of the knob 18 yfrom the movement is imparted to the inside of the door.

ln practice, I have found that the employment of two studs produces an unusually strong, rigid and dependable construction, though, if desired, a sinole stud or more than two may be employe The lock ot the present invention maybe employed es an entirety. s thus far decribed, the slide 15 being locked against inadvertent movement at both terminii of its travel by the cam 20, 'which it will be noted from Figures 2 and 3, is, at these times, on dead centers. However, in order to assure amore permanent and positive locking of the slide l5,"particularly by unauthorized persons` through "the ernpgoy. ment of a jimmy-or the like, additional and positive locking means is preferably provided. This ineens moy, in practice, con.- renently partake of e form of e @implemenbut, is?

2. A door lock embodying a casing adapted to be mounted on one side of a door so as to project beyond the edge thereof and provided adjacent one end with an opening positioned beyond the edge of the door. a mova ein uber within the casing and also provided with an opening, and means for moving said member to bring the opening of the member into and out of registration with the'openim,r ot the casing, in combt nation with a hook shaped keeper intended to be mounted on one side of the door jamb in the path of the opening ofthe casing end adapted, when the door is swung shut, with the opening of the movable member in registration with the opening otthe casing, to pass through said opening and into the casing, whereupon the movement of said member will shift the same into a position wherein the openings are out of registration to cause the hook shaped keeper to hoolr over the movable member and preclude separetion of the casing and keeper und keep the door closed until the opening' of the movable member is returned to registration with the opening of the casing, and means for locking the movable member against movement except that imparted thereto by the operating means for said member.

3. door lock embodying a casing adepted to be mounted on one side of a door to project beyond the edge thereof, s slidinof member mounted to slide longitudinally o? the casinmr and having a head substantially equal in width to the interior width of' the casing, said head being provided with an opening, e keeper adapted to be mounted on one side of the door jamb and having a hookshaped projection adapted, when the door is swung shut with the opening in the head in a predetermined position, and pass through and beyond the opening in said head, and means for shifting the head longitudinally ofthe casing to cause the head to interlock with the honlt-shaped projection of the keeper.

4. A door lock embodying a casing adapted to be mounted on one side of a door to project beyond the edge thereof and provided on both its front and back with juxteposed openings positioned beyond the edge of the door, a sliding member operable within the casing and provided at one of its ends with an opening, means for sliding the recante longitudinally of the casing shifts the open 1 ing of said sliding member into .e position out of alinement with thelopeningsin the casing for the purpose of locking the sliding member to the keeper.

5. A. door lock embodying s casing ed to be mounted on one side ot a door' tol project beyond the edge thereof und provided with juxtaposed openings in the iront and baclrbeyond the edge oit the door, s keeper adapted to be mounted ou the door jamb and provided with a hook-shaped pro jection adapted, when the door is swung shut, to pass through both openings of the casing with a portion ot the keeper projection housed within the casing in concealed position, and s sliding plate positioned with# in the casing and adapted to be slid into position to interlock with the lioolr sbsped keeper projection when snidpro'jeetion 'is extending through the openings in the casing. 6. A door lock embodying sensing; edaptn ed to be mounted on one side ot' at door to project beyond the edge thereof end pro vided in its from and time with esteemed openings, a keeper adapted to he moin-ated on the door amb and provided with n projection having an enlarged heed.j 'which projection is adapted when the door is swung shut, to pass through 'both openings inthe. casing, the opening in the front oit the cas' ing being of substantially the same rend shape as the enlarged heed ot the keeper projection, whereby all of the keeper projection except the head is concealed Within the casing when said projection is extending through the openings in the casing., and ya sliding plate operable Within the casing and adapted, through slidingl movementva to interloclr with the keeper projection ttor the purpose of locking the casing to the keeper. In testimony whereof l have signedgthe foregoing specification.
